SSMS Addin - GetHierarchy方法爲NULL

Question

我正在爲SSMS 2014編寫插件。我想要在ObjectExplorer中獲取搜索項目的層次結構。 但GetHierarchy方法爲空。有沒有人有任何想法？

ObjectExplorerService objExplorerService = (ObjectExplorerService)ServiceCache.ServiceProvider.GetService(typeof(IObjectExplorerService)); 
MethodInfo getHierarchyMethod = objExplorerService.GetType().GetMethod("GetHierarchy", BindingFlags.Instance | BindingFlags.NonPublic); 

Answer 1

我找到了我的問題的答案。我用下面的代碼訪問了「Object Explorer Hierarchy」。

List<IExplorerHierarchy> hierarchyList = new List<IExplorerHierarchy>(); 
ObjectExplorerService objExplorerService = (ObjectExplorerService)ServiceCache.ServiceProvider.GetService(typeof(IObjectExplorerService)); 
System.Type t = objExplorerService.GetType(); 

PropertyInfo getHierarchyMethod = t.GetProperty("Tree", BindingFlags.Instance | BindingFlags.NonPublic); 
var value = getHierarchyMethod.GetValue(objExplorerService, null); 

PropertyInfo getHierarchyMethod2s = value.GetType().GetProperty("Hierarchies", BindingFlags.Instance | BindingFlags.NonPublic); 
var value2 = getHierarchyMethod2s.GetValue(value, null); 

foreach (var item in (Dictionary<string, IExplorerHierarchy>)value2) 
{ 
    hierarchyList.Add(item.Value); 
}
